Winter Cover Crop Stewardship Program
The Winter Cover Crop Stewardship Program helps farmers establish vegetative cover on their fields before winter. The cost of planting is shared by the farmer and DF&WT. Winter cover crops are beneficial because they:
- Provide feeding habitat for herbivorous waterfowl and shorebirds
- Protect the soil from erosion due to heavy winter rain
- Scavenge excess nutrients like nitrogen before they leach from the soil
- Increase organic matter in the soil, thereby improving soil structure

After farmers harvest their main summer crop, they prepare the soil and plant a cover crop. Cover crops are usually planted in late August and early September.
Cover crops protect soil from heavy rains and shade out weeds. In spring, the cover crop can be ploughed under to provide a green manure for the soil. Clover (above) can also fix nitrogen, an important plant nutrient.
